Abstract
The invention provides a spherical surface trimming tool. A round column at the middle of a mill knife core shaft is arranged in an inner hole at the upper edge of a spherical surface trimming knife; the spherical surface trimming knife is fixedly arranged on the mill knife core shaft by virtue of an internal thread at the lower edge of the spherical surface trimming knife and the lower end surface of the spherical surface trimming knife; a gap between a round column at the upper edge of the mill knife core shaft and the inner hole at the upper edge of the spherical surface trimming knife is 2-5mm; the cross edge of the upper end surface of the spherical surface trimming knife and the inner hole of the spherical surface trimming knife is kept sharp; the spherical surface trimming knife is used for performing thermal treatment so as to achieve 58-62HRC; center holes are reserved at two ends of the mill knife core shaft; the mill knife core shaft is used for performing thermal treatment and tampering so as to achieve 33-38HRC; the center holes at the two ends of the mill knife core shaft are B-type center holes with protective cones; and the spherical surface trimming knife is used for manufacturing high-speed tool steel. The spherical surface trimming tool has the following advantages: a spherical body with high surface quality and a standard shape can be processed on a general machine tool; and the spherical surface trimming knife is conveniently subjected to tool sharpening on the mill knife core shaft; and the spherical surface trimming tool is low in manufacturing cost and high in economic benefit.
Description
Technical field
The present invention relates to metal cutting tool, especially the Aspherizing instrument.
Background technology
End at the rod part of some machines has ball, these balls generally at lathe with the longitudinal feed slide carriage of mobile lathe and the method car of the middle carriage of crossing feed become simultaneously.Even if the workman of skilled operation, the shape that also will repeatedly conscientiously check, repeatedly repair the ball that also is difficult to the standard that reaches with model.
Summary of the invention
The purpose of this invention is to provide a kind of Aspherizing instrument, is the geometrical principle of circle according to the cross section of ball, with the rib that endoporus and the end face of Aspherizing cutter forms, the spherome surface of turning is accomplished the sphere of standard.
The objective of the invention is to realize as follows:
Cylinder in the middle of the sharpening mandrel be contained in the Aspherizing cutter the endoporus of top in, the Aspherizing cutter is fixed on the sharpening mandrel by internal thread and the lower surface of Aspherizing cutter bottom, the gap of the endoporus of the cylinder of sharpening mandrel top and the top of Aspherizing cutter is 2 millimeters～5 millimeters, it is sharp that the friendship rib of the endoporus of the upper surface of Aspherizing cutter and Aspherizing cutter keeps, Aspherizing cutter heat treatment 58～62HRC, sharpening mandrel two ends keep centre bore, sharpening mandrel heat treatment quenching and tempering 33～38HRC.
Sharpening mandrel two ends centre bore protects the Type B centre bore of cone for band.
Aspherizing cutter high-speed tool steel making.
The advantage of this Aspherizing instrument is: just can process the surface quality height, the spheroid of shape criteria at machine tool with the Aspherizing cutter of Aspherizing instrument.The Aspherizing cutter is contained on the sharpening mandrel, and sharpening is very convenient.The cutter low cost of manufacture, economic benefit is high.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the structure chart of Aspherizing instrument.
1. Aspherizing cuttves, 2. sharpening mandrel among the figure.
The specific embodiment
In the accompanying drawings,
The Aspherizing instrument is comprised of Aspherizing cutter (1) and sharpening mandrel (2).As the operator at lathe with the longitudinal feed slide carriage of mobile lathe simultaneously and the middle carriage of crossing feed, the part semi-finished vehicles is become the basic configuration of spheroid after, the operator arrests Aspherizing cutter (1) with hand and again sphere is accomplished smooth standard shape.When making Aspherizing cutter (1), be fixed on its endoporus of grinding on the grinding machine with internal thread and the lower surface of its bottom.Behind the blade blunt of Aspherizing cutter (1), cylinder in the middle of the sharpening mandrel (2) is contained in the endoporus of top of Aspherizing cutter (1), Aspherizing cutter (1) is fixed on the sharpening mandrel (2) by internal thread and the lower surface of Aspherizing cutter (1) bottom.Sharpening mandrel (2) withstands on the logical cylindrical grinder with the centre bore at its two ends, with the end face of the side grinding Aspherizing cutter (1) of the emery wheel of grinding machine, make the friendship rib of endoporus of the top of the upper surface of Aspherizing cutter (1) and Aspherizing cutter (1) keep sharp.Convenient for sharpening, the gap of the endoporus of the cylinder of sharpening mandrel (2) top and the top of Aspherizing cutter (1) is 2 millimeters～5 millimeters.In order to improve the service life of Aspherizing cutter, Aspherizing cutter (1) adopts high-speed tool steel making and heat treatment 58～62HRC.Sharpening mandrel (2) two ends keep centre bore for being with the Type B centre bore that protects cone, sharpening mandrel (2) heat treatment quenching and tempering 33～38HRC.
Claims (3)
1. Aspherizing instrument, comprise Aspherizing cutter and sharpening mandrel, it is characterized in that: the cylinder in the middle of the sharpening mandrel be contained in the Aspherizing cutter the endoporus of top in, the Aspherizing cutter is fixed on the sharpening mandrel by internal thread and the lower surface of Aspherizing cutter bottom, the gap of the endoporus of the cylinder of sharpening mandrel top and the top of Aspherizing cutter is 2 millimeters～5 millimeters, it is sharp that the friendship rib of the endoporus of the upper surface of Aspherizing cutter and Aspherizing cutter keeps, Aspherizing cutter heat treatment 58～62HRC, sharpening mandrel two ends keep centre bore, sharpening mandrel heat treatment quenching and tempering 33～38HRC.
2. Aspherizing instrument according to claim 1 is characterized in that: described sharpening mandrel two ends centre bore protects the Type B centre bore of cone for band.
3. Aspherizing instrument according to claim 1 is characterized in that: described Aspherizing cutter high-speed tool steel making.
